Zsh & RVM woes (rvm-prompt doesn't resolve)

阅读更多关于 Zsh & RVM woes (rvm-prompt doesn't resolve)

I recently saw the light and changed over to Zsh. I naturally used Oh My Zsh to configure it, as I'm noobish. So, there are several themes that have an rvm-prompt included and here is were my problems began. Everytime I load Zsh I have to rvm reload or else rvm-prompt is not resolved ( zsh: command not found: rvm-prompt ). Note that it resolves fine after I reload. Also, and in line, when I go to a directory that has its own .rvmrc (other gemset) and then I come out of it, the same problem occurs; I'm left with having to reload Zsh again. I have RVM in $PATH set. I have [[ -s "$HOME/.rvm

zsh history is too short

阅读更多关于 zsh history is too short

When I run history in Bash, I get a load of results (1000+). However, when I run history the zsh shell I only get 15 results. This makes grepping history in zsh mostly useless. My .zshrc file contains the following lines: HISTFILE=~/.zhistory HISTSIZE=SAVEHIST=10000 setopt sharehistory setopt extendedhistory How can I fix zsh to make my shell history more useful? UPDATE If in zsh I call history 1 I get all of my history, just as I do in Bash with history . I could alias the command to get the same result, but I wonder why does history behave differently in zsh and in Bash. The OP has already

Is there a hook in Bash to find out when the cwd changes?

阅读更多关于 Is there a hook in Bash to find out when the cwd changes?

问题 I am usually using zsh, which provides the chpwd() hook. That is: If the cwd is changed by the cd builtin, zsh automatically calls the method chpwd() if it exists. This allows to set up variables and aliases which depend on the cwd. Now I want to port this bit of my .zshrc to bash, but found that chpwd() is not recognized by bash. Is a similar functionality already existing in bash? I'm aware that redefining cd works (see below), yet I'm aiming for a more elegant solution. function cd() {

Z Shell “autoload” builtin - what is it good for?

阅读更多关于 Z Shell “autoload” builtin - what is it good for?

I have been using the Z shell for a while now, and I am starting to be curious. One thing I have stumbled at when writing my own functions is "autoload". According to the zshbuiltins(1) man page autoload is "equivalent to functions -u " (with an exception), which is "equivalent to typeset -f " (with an exception). However, after looking at the autlooad use of, say functions/Prompts/promptinit , I think I have an idea what it does. I think of autoload as, well, kind of "import" statement. But why is "autoload foo" superior to "source bar"? I don't get that. Marcus Borkenhagen As stated in the

How to edit path variable in ZSH

阅读更多关于 How to edit path variable in ZSH

问题 In my .bash_profile I have the following lines: PATHDIRS=" /usr/local/mysql/bin /usr/local/share/python /opt/local/bin /opt/local/sbin $HOME/bin" for dir in $PATHDIRS do if [ -d $dir ]; then export PATH=$PATH:$dir fi done However I tried copying this to my .zshrc , and the $PATH is not being set. First I put echo statements inside the "if directory exists" function and I found that the if statement was evaluating to false, even for directories that clearly existed. Then I removed the

阅读更多关于 Unable to have Bash-like C-x-e in Zsh

问题 I found the following command in Bash which Zsh does not have in the same buttons at the thread. Ctrl-x-e It opens the current input in terminal to an editor. How can you have the same command in Zsh? 回答1: I'm using it with VIM mode. Basically ESC-v (or simply v if already in command mode) opens the terminal. It is setup by: autoload -U edit-command-line zle -N edit-command-line bindkey -M vicmd v edit-command-line Here is how to setup it in emacs mode: autoload edit-command-line zle -N edit

How can I get 'git status' to always use short format?

阅读更多关于 How can I get 'git status' to always use short format?

问题 I'd like git status to always use the short format: $ git status --short M file1 M dir/file2 ?? file_untracked3 ?? dir/file_untracked4 There doesn't seem to exist a configuration option for this, and git config --global alias.status "status --short" does not work. I haven't managed to create an alias in zsh either. How can I make git status to use the short format by default? 回答1: Starting git1.8.4 (July 2013), you can configure git status to use short by default. See commit
